Tranexamic Acid Precautions: Be Sure to Check Before Use

To state the conclusion first, tranexamic acid is a highly safe ingredient widely used even in dermatology clinics, but depending on the method of use, concentration, and skin condition, some people may experience dryness or irritation, so caution is needed. In particular, if you have sensitive skin or use it together with other active ingredients (high-concentration vitamin C, retinol, etc.), it's a good idea to check for irritation reactions in advance. This article summarizes what to be careful of when using tranexamic acid, and home care methods that can help when your skin becomes sensitized.

What is Tranexamic Acid, and Why is 'Caution' Needed?

Tranexamic acid is an ingredient widely used in cosmetics for skin tone care purposes, and is often used as one of the functional raw materials registered with the Ministry of Food and Drug Safety. However, like all ingredients, when combined at high concentrations or used together with other irritating ingredients, it can put a burden on the skin barrier.

In particular, if used when the skin barrier is weakened after cleansing, or during a period when the stratum corneum has thinned, you may feel irritation or dryness more intensely than usual. This is often caused by the interaction between skin condition and usage method, rather than being a problem with the ingredient itself.

Changes That May Occur Depending on the Period of Use

When you first start using tranexamic acid, your skin may experience temporary dryness or tightness as it adapts to the ingredient. During this period, it is safer to start with a small amount and observe how your skin responds.

During weeks of continuous use, skin reactions can vary from person to person. Some people continue using it without any particular discomfort, while those with sensitive skin may continue to experience flaking or irritation, making it necessary to reconsider whether to keep using it.

In the stage of ongoing use, combining moisturizing and soothing care can help maintain healthy skin condition.

Home Care Principles to Follow When Using Tranexamic Acid

First, when using it for the first time, it is advisable to apply it to a small area rather than the entire face to check for any reaction.

Second, avoid using high-concentration active ingredients (such as retinol or high-concentration vitamin C) together with tranexamic acid at the same time; alternating them on different days can help reduce irritation.

Third, if dryness or tightness is felt during use, sufficient moisturizing care should be combined. In particular, ingredients with a composition similar to skin lipids, such as ceramides and panthenol, can help with barrier care.

Fourth, if stinging or redness persists, it is safer to stop use immediately and consult a dermatologist.

Post-Procedure Recovery Depends on Home Care

When using active ingredients like tranexamic acid, combining moisturizing and soothing care to prevent the skin barrier from becoming sensitive can be helpful. During sensitive periods such as right after a procedure, you can prioritize redness and barrier care with 'Ultra Cera-Rich Cream,' and then continue with deep hydration and skin texture care using 'Hydro Re-Boosting Cream' during the recovery period, following this 2-STEP routine.
